Write your header file which includes your classes, functions, etc. Rename the file to .h extension. In your main.cpp, include the header file. #include "myheader.h" You may also want to look at the preprocessor directives which you may need to include in the header file. https://stackoverflow.com/questions/3246803/why-use-ifndef-class-h-and-define-class-h-in-h-file-but-not-in-cpp
